Introduction

Solar panels are a powerful and effective way to lower energy costs and help the environment, but they need the right kind of protection.

Severe weather, especially hail, can do a lot of damage to solar panels and decrease their efficiency. Hail protection especially using hail netting is important for any solar panel owner, but it’s especially critical for those who live in areas prone to bad weather events.

Taking steps to protect solar panels from hail damage can help you keep your investment in solar power safe for years to come.

By following these tips, you can be sure that your solar panels will be protected from the worst Mother Nature offers.

Here are 7 tips to help you keep your solar panels safe from hail

Which situations require hail protection for solar panels?

Determine the Hail Possibility and Frequency in Your Area.

If you live in a hail-prone area, being prepared for the possibility of hail damage is a must.

One of the best ways to do this is to research the hail frequency in your area. This will give you a good idea of how often you need to take steps to protect your solar panels and study how to protect solar panels from hail.

According to the National Severe Storms Laboratory (NSSL), more than 50,000 thunderstorms occur in the U.S. every year, and about 10% of those storms produce hail.

Most of the time, hail is small and causes little or no damage.

But occasionally, hailstones can be large and cause significant damage to property, including solar panels.

In the United States, areas, where hailstorms are common, are located in the Midwest, Great Plains, and Rocky Mountain states.

However, hailstorms can occur anywhere in the country.

The most frequent hail areas in Australia are in the south-eastern and eastern states.

Hail Size Matters

The size of the hailstones is what causes damage, not the number of them. For example, suppose your area experiences a hailstorm with golf ball-sized hailstones (1.75 inches in diameter). In that case, that is more likely to cause damage to solar panels than a storm with pea-sized hailstones (0.25 inches in diameter).

NSSL researchers have found that the vast majority of hailstorms produce small hailstones, less than 0.75 inches in diameter.

In fact, about 80% of all hailstones are smaller than this.

However, about 20% of all hail stones are larger than 0.75 inches in diameter. And a very small percentage of hailstones, less than 0.1%, is extremely large, with a diameter of 2 inches or more.

These large hailstones are most likely to damage solar panels severely and affect energy output.

7 Tips about How to protect solar panels from hail

There are a few ways to make your solar panels more resistant to hail storm.

Install hail-proof netting

The easiest and most effective way is to install a solar panel protective cover for the solar panels.

The netting is placed over the solar panels and helps to deflect hail storms.

Hail netting is the most effective protective cover when used with other hail protection methods, such as impact-resistant mounts.

Installing hail netting is like investing in insurance, spending a small amount of money to avoid huge losses, and being cost-effective.

Choose the right high quality solar panels

Choose the right material to make solar panels withstand hails.

Solar cells are the most crucial solar panel components.

When shopping for solar panels, it’s important to choose a durable material that can withstand severe weather conditions.

Polycrystalline and monocrystalline silicon are two of the most durable solar cells materials available.

They are also less likely to be damaged.

Choose the Right Location for Your Solar Panels

When you’re installing solar panels, take hail frequency into consideration.

If you live in an area that is prone to hail, it’s best to avoid putting your solar panels in a spot that is directly in the path of severe storms.

Use tempered glass

 In addition to the solar cells, standard solar panels also include a glass casing in front of the panels, which are usually 6-7 mm thick and susceptible to hail damage.

When hailstones hit the glass surface, they can break it, reducing the solar panel’s power output. In some cases, hail can shatter the entire panel. Tempered glass is a type of glass that is designed to be more resistant to breakage.

If you have had repeated hailstorms near your PV farm site, using tempered glass for your solar panels can help protect them from damage to the solar system.

Use impact-resistant mounting and racks

Using impact-resistant mounts and racks can help protect solar panels from hail damage. These products are designed to absorb the impact of hailstones, which can help prevent breakage.

Select a strong tilt angle when installing solar panels

Choosing a tilt angle that will help protect your solar panels from damage is important. A steeper tilt angle will help deflect hail storms away from the solar panel.

Consider Wind and Hail Insurance

Consider the solar panel insurance for the wind and hail in your area when you’re shopping for solar panels. If you live in an area that is prone to severe storms, it’s a good idea to get insurance to help protect your investment.

Insurance

When you’re shopping for insurance, be sure to get a policy that covers hail damage. Some policies only cover wind damage, so be sure to read the fine print.

Also, be sure to shop around and compare rates. Some insurers offer discounts for solar panel owners, so it’s worth checking with your insurance company to see if they offer any special rates.

How to Choose Hail Netting?

What is Hail Netting?

It’s a type of hail protection that is placed over solar panels to help deflect hail storms. Hail netting is most effective when used in conjunction with other hail protection methods, such as impact-resistant mounts.

What’s the material of hail nets?

Hail nets are usually made of polyethylene monofilament. This material is strong and durable and suitable for outdoor use. Even if it is exposed to wind and rain for a long time outdoors, the effect of use will not be affected.

What’s the best type of Hail Netting for a solar panel?

There are three main types of hail netting in the market: Raschel Drap Hail Netting, Raschel Quad Crossover Knitted Hail Netting, and Leno Hail Netting. They are different in their construction and characteristics due to the different equipment and methods used to weave them.

Leno Hail Netting is usually chosen for solar panel protection because its larger mesh provides less light blockage when protecting against hail and has a 93-95% sunlight transmission rate.

What’s the best color of Hail Netting used in solar panels?

The color of transparent is the most suitable color for anti-hail netting installed on solar panels, as they are the most favorable for light penetration. The transparent color protects the solar panels as much as possible while at the same time minimizing the impact on the efficiency of the solar panels. Therefore, most PV farms choose transparent hail netting for the purpose of protecting solar panels.
